This just totally brightened up our day! The cast of Pitch Perfect will be REUNITING at the 2013 MTV Movie Awards.

BETTER YET, they’ll be PERFORMING in the opening number with the show’s host and fellow co-star Rebel Wilson. Prepare to catch Anna Kendrick, Brittany Snow, Anna Camp, Skyler Astin, and the rest of the group sing a mash-up of the songs from the film.

AH-MAZING!!

The film — that has already joined the ranks of cult classics — also happens to be nominated for four MTV Movie Awards: Best Female, Best Breakthrough Performance, Best Musical Moment, and Best WTF Moment.

Update: Anna Kendrick's rep has confirmed that the actress will unfortunately not be attending the MTV Movie Awards. She will be in NYC working on her latest film project The Last Five Years. Too bad! We were so hoping for a proper Pitch Perfect reunion!
